Description

Technical Field

[0001] This utility model relates to the field of corrugated water filter pipe technology, and in particular to a DKPE double-wall corrugated water filter pipe for water wells. Background Technology

[0002] Corrugated filter pipes are a common type of specialized pipe used in groundwater wells, drainage systems, and groundwater recovery projects, serving the dual functions of filtration and drainage.

[0003] A search revealed a high-strength plastic corrugated water filter pipe with publication number CN220286796U. The pipe includes a corrugated body with a first filter hole and a second filter hole at the troughs and crests of the corrugated body, respectively. The first filter hole is a tapered structure that gradually increases in size from the outer wall to the inner wall. The second filter hole includes a straight hole and inlet holes located on both sides of the straight hole and communicating with it. The inlet holes are obliquely located on the upper and lower sides of the crests, and their diameter gradually increases from the outside to the inside. This invention uses a tapered structure for the filter holes at the troughs. With this structure, impurities entering through the tapered inlet can pass smoothly through the filter holes without lingering, thus reducing the possibility of impurities clogging the filter holes.

[0004] The device in the published patent is inconvenient to install, and assembling multiple water filter pipes is time-consuming and laborious, resulting in low practicality. Utility Model Content

[0005] In response to the technical problems of existing patents, such as inconvenient installation of devices, time-consuming and labor-intensive assembly of multiple filter pipes, and low practicality, this utility model provides a DKPE double-wall corrugated filter pipe for water wells.

[0006] The technical solution adopted by this utility model is: a DKPE double-wall corrugated water filter pipe for water wells, comprising:

[0007] The main body of the water filter pipe;

[0008] An assembly assembly is installed at both ends of the water filter pipe body, and the assembly assembly is used for positioning and assembling multiple water filter pipe bodies;

[0009] The assembly assembly includes guide structures installed at both ends of the filter pipe body and an assembly structure installed on the outer wall of the filter pipe body.

[0010] Furthermore, the guiding structure includes a guide groove formed at one end of the filter pipe body and a guide post fixedly welded to the other end of the filter pipe body, the guide post cooperating with the guide groove.

[0011] Furthermore, the assembly structure includes an assembly base fixedly welded to the outer wall of one end of the filter pipe body, an assembly component installed inside the assembly base, a positioning base fixedly welded to the outer wall of the other end of the filter pipe body, and a positioning block fixedly welded to one side of the positioning base.

[0012] Furthermore, a positioning groove is provided on one side of the positioning seat, and a reset groove is provided on one side of the positioning groove. The assembly includes a reset plate fused to the inner wall of the reset groove by a reset spring, a reset post and a limiting post fixedly welded to the top of the reset plate, and an assembly post fixedly welded to the top of the reset post.

[0013] Furthermore, the positioning block cooperates with the positioning groove, and a limiting hole is formed on the positioning block, with the limiting post cooperating with the limiting hole.

[0014] Furthermore, the main body of the water filter pipe includes a smooth inner wall and a corrugated outer wall, both of which are provided with water filter holes, and a water filter layer is installed between the smooth inner wall and the corrugated outer wall.

[0015] The beneficial effects of this utility model are:

[0016] The guide groove and guide column work together to guide the position of the two filter pipe bodies. The assembly column drives the reset column to move, the reset column drives the reset plate to squeeze the reset spring, and the reset plate drives the limit column to move. The relative position of the limit column and the limit hole is controlled, and then the relative position of the positioning block and the positioning groove is controlled. This makes it easy to assemble multiple filter pipe bodies. It is simple, convenient and practical. Attached Figure Description

[0026] The following is in conjunction with the appendix Figs. 1-3 The present invention will be further described below.

[0027] To address the problems existing in the background art, this application proposes the following technical solution:

[0028] A DKPE double-wall corrugated filter pipe for water wells includes: a filter pipe body 1 and an assembly component 2;

[0029] The main body of the water filter pipe 1 includes a smooth inner wall 10 and a corrugated outer wall 11. Both the smooth inner wall 10 and the corrugated outer wall 11 are provided with water filter holes 12, and a water filter layer is installed between the smooth inner wall 10 and the corrugated outer wall 11.

[0030] The filter layer is the filler material between the smooth inner wall 10 and the corrugated outer wall 11, such as gravel, non-woven filter cloth or special ceramic granule filter media, or the filter slits opened on the corrugated outer wall 11 itself can be used as the filter medium.

[0031] like Figs. 1-3 As shown, the assembly component 2 is installed at both ends of the filter pipe body 1. The assembly component 2 is used for positioning and assembling multiple filter pipe bodies 1.

[0032] The assembly component 2 includes a guide structure 201 installed at both ends of the filter pipe body 1 and an assembly structure 202 installed on the outer wall of the filter pipe body 1.

[0033] Furthermore, the guide structure 201 includes a guide groove 2011 formed at one end of the filter pipe body 1 and a guide post 2012 fixedly welded to the other end of the filter pipe body 1, the guide post 2012 cooperating with the guide groove 2011.

[0034] Furthermore, the assembly structure 202 includes an assembly base 2021 fixedly welded to the outer wall of one end of the filter pipe body 1, an assembly component 2022 installed inside the assembly base 2021, a positioning base 2023 fixedly welded to the outer wall of the other end of the filter pipe body 1, and a positioning block 2024 fixedly welded to one side of the positioning base 2023.

[0035] Furthermore, the positioning seat 2023 has a positioning groove 3 on one side and a reset groove on the other side. The assembly 2022 includes a reset plate 5 fused to the inner wall of the reset groove by a reset spring 4, a reset post 6 and a limiting post 7 fixedly welded to the top of the reset plate 5, and an assembly post 8 fixedly welded to the top of the reset post 6.

[0036] Furthermore, the positioning block 2024 cooperates with the positioning groove 3, and a limiting hole 9 is provided on the positioning block 2024, with the limiting post 7 cooperating with the limiting hole 9.

[0037] Working principle: During use, the corrugated outer wall 11 increases the rigidity and strength of the filter pipe body 1, enhancing its resistance to external pressure and mechanical loads. The smooth inner wall 10 reduces water flow resistance and ensures flow efficiency. The filter holes 12 effectively block sand and gravel, preventing blockage. Groundwater enters the pipe through the filter holes 12 and filter gaps, while larger particles such as sand and silt are blocked outside the pipe, thus preventing impurities from entering the pipe and affecting water quality or clogging the pipe.

[0038] During the assembly process, the guide groove 2011 and guide column 2012 cooperate to guide the position of the two filter pipe bodies 1. The assembly column 8 drives the reset column 6 to move, the reset column 6 drives the reset plate 5 to squeeze the reset spring 4, and the reset plate 5 drives the limit column 7 to move, thereby controlling the relative position of the limit column 7 and the limit hole 9, and thus controlling the relative position of the positioning block 2024 and the positioning groove 3. This facilitates the assembly of multiple filter pipe bodies 1, is simple and convenient, and has good practicality.

[0039] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
